Crossing requires focus on one niche, whole product, and trusted channels.
Leadership in one segment creates the credibility to expand to adjacent markets.

Chasm exists because early and mainstream buyers need opposite evidence.
D-Day strategy: concentrate resources, win beachhead, then bowling alley expansion.

Positioning and distribution matter more than features during crossing.
